A'telephonic apparatus for deep sea diving, in accordance ,with this invention, includes a tenders and a divers telephone system and each of which is of the magnetic type.

The 'tenders telephone system comprises a transmitter 1 for the use of the tender and a pair of receivers 2, 3 for the use of the diver,

transmitter 4 for the use of the diver and a pair of receivers 5, 6 for use by the tender. Both systems are of reduced sensitivity. The electrical elements of the transmitters and receivers are of like construction, with parts interchangeable, and articulation may be made over the receivers and heard on the transmitters. The systems are connected in parallel over a twin conductor and operatedwithout the employment of batteries or any other external source of'electrical power.

.As the electrical elements ofthe transmit ters and receivers are similar, it is to be understood that the showing of Figure 6 applies to both transmitters and the several 1'eceivers and each transmitter and each receiver includes a pair of field coils 7, 8 connected together as at 8, Figure 5, a pair of superposed permanent magnets 9,10 of substantially horseshoe-shape positioned on a combined supporting and spacing plate 11 and surrounding the coils 7, 8, a clamping member 12 corresponding in shape to the shape of the magnets and positioned upon the upper magnet, holdfast devices 13, binding posts 14, 1:"; in circuit with the, coils, and a diaphragm 1(3. The plate 11 is of skeleton form and carries the coils 7, 8. The coils 7, 8, magnets 9, 10, plate 11, clamping member 12 and binding posts 1 1, 15 are arranged within an open top casing 17 of annular form. The plate 11 is positioned upon the upper face of the bottom of the casing 17. The inner edge of the clamping member 12 is formed with a pair of oppositely extending apertured lugs 18. The holdfast devices 13 extend up through the bottom of the casing 17, through the plate 11 and are coupled to the lugs 18. The heads of the holdfast devices 13 are positioned against the lower face of the bottom of the casing 17.

Thediaphragm 16 is mounted upon the edgeof the body of the casing 17 and is arranged in spaced relation with respect to the coils 7, 8. Positioned within the casing 17 is a block of insulation 19 to which the binding posts 14., 15 are attached The body of the casing is formed with an opening 20 for the passage of the circuit conductors 21, 22 which are attached to the binding posts 14, 15. The circuitconnections21,22 are euclosedbyasheat hing 23 of water proof material and said connections 21, 22 are also insulated. The sheathing 23 further acts as an insulating means and is in the form of a flexible casing impervious to moisture. The sheathing 23 frictionallyengages with the wall of the opening 20. The body of the casing 17 is formed with peripheral threads for connectin therewith a clamping member orcap 24 o insulation and which acts to fixedly secure the diaphragm 16 in position. The clamping member or cap 24 is formed with a centrally dispo'sed opening 25 of appropriate diameter and the outer face thereof 15 concaye as indicated at 26. The clamping member or cap 24 is flanged as at 27 and the inner face of the latter is threaded for engagement with the peripheral threads of the casing 17. The flange 27 is notched as at 28 for the passage of a retaining screw 29 which engages in the casing 17. SeeFigure 4. The screw 29 acts as a means to lock the clamping member or cap 24 from shifting after it has been positioned or connected to the casing 11'.

The diaphragm 16 is about .0065 of an inch in thickness. Each of the field coils is about two ohms and when combined will equal substantially four ohms. The inner face of the casing 17 is provided with a coating 30 of waterproof material and said coating extends over the member 12, field coils, inner sides of the magnets and upper face of the plate 11. The elements within the casing 17, as well as the inner face of the latter, are thoroughly coated to prevent moisture or water attacking the same. The plate 11 is also connected to the bottom of the casing 17, by an upstanding screw 31 having its head positioned against the lower face of the bottom of the casing. The coil windings are of much shorter lengths of Wire and of a slightly larger size than the coil windings employed in telephones of the magnetic type.

The permanent mag-nets have a strength superior to that of the magnets of ordinary telephones. The wire employed in the coils is enameled and 30, B. S. The cores of the coils are soft iron. Any suitable means can be employed for coating the interior of the casing 17 and the elements arranged therein for the purpose of making them thoroughly waterproof.

With reference to Figures 1, 12 and 13 the casings which enclose the circuit connections from the "receivers 5, 6 and which are indicated at 32, 33 extend into a four-way coupling formed of two sections 34, 35. The circuit connections 21 projecting from the casings 32, 33 are coupled together as at 36 to a conductor 37 and leading therefromis a conductor 38. The circuit connections 22 extending from the casings 32, 33 are coupled together as at 39 to a conductor 40 and leading from-the latter is a circuit conductor 41. The conductors 38 and 41 are connected in parallel by a casing 42 constructed in the same manner as the sheathing 23. The receivers 5, 6 as before stated are a part of the divers telephone system. The transmitter- 1 has a casing 43 extended therefrom and which encloses circuit connections 44, 45. The casing 43 possesses the same characteristics as the sheathing 23 and extends-into the sections 34, 35 of the four-way coupling. The circuit connection 44 is coupled with the circuit conductor 41 as at 46 and the circuit connection is coupled with the circuit conductor 38 as at 47. The conductors 37 and 40 are secured to a block 48 of insulation which is positioned within the section 35 of .is in electrical connection with the circuit conductors 41, 38. The plug 54 of the section 51 engages a contact 55 which is electrically connected with a circuit conductor 56. forming a continuation of the circuit conductor 41. A circuit conductor 57 forms a continuation of the circuit conductor 38 and is electrically connected with the latter through the coupling 57 and plug 54. The plug 54 is insulated and is of known construction, that is to-say the plug 54 is formed of two elements, one of which is electrically connectedto the circuit conductor 41 and the other section to the circuit conductor 38. The coupling 57 is electrically connected with that part of the plug 54 which is electrically connected with the circuit conductor 38. The apparatus includes what may be termed a llne formed of two sections, one section of'which carries the plug section 50 of the jack and such line section which carries the plug section 50 extends from the four-way coupling 59 and the other line section carries the socket section 53 of the jack 51 and such line section which carries the socket section 53 extends from the divers helmet 60. By this arrangement either line section can be of any length desired, but preferably the line section which extends from the divers helmet 60 is of greater length than the other line section.
